Liquid Propane Gas Conversions - Are they worth it?

Conversion is actually modifying an equipment which is not designed for it.

Gasoline for my gasoline engine,
Diesel for my diesel engine,
LPG for my OVEN.

That's a fact.

*Power loss - just about everyone complains about LPG power loss and
just about everyone has their own theory. Mine is that becuase of the
large volume of gaseous fuel in the induction stroke, the volume of
oxygen in the induction stroke is displaced (in comparison to the
air/fuel ratio when using liquid fuel). The fuel starts the burn but
the oxygen keeps it going, to take out some of the oxygen and voila -
less power.
As LPG has an octane rating of about 97, you can advance
the ignition timing slightly to take advantage of this, lessening the
power loss a little bit.

*Valve wear. If your engine was
designed to run on regular leaded fuel, you need to replace the
lubricating properties of the lead in your induction mixture when you
use LPG - just like you SHOULD when you use unleaded. Failure to do so
will prematurely wear the valve guides & seats. The expensive
solution is to have the head rebuilt with stailess guides & seats,
the cheap way is to use a produce such as VALVESAVER - which allows a
small amount of lubricant to be sucked in with the induction mixture.

*Consuption
- even though you are saving 50% on the COST of the fuel, you generally
will use 30% more fuel. Our Mitsubishi Magna goes 800km on 75 litres of
petrol OR 450km on 50 litres of LPG. You use more but you pay less. The
offest in cost will pay itself off... eventually!

*Bomb in the
back? There are many stories about LPG tanks exploding and incinerating
the vehicle occupants, but in reality it is much safer than having a
tank full of petrol in the car. (read: urban myth) The tanks are
manufactured to high quality controlled standards and require periodic
inspection to ensure they are in safe order. If you had seen the metal
thickness & welding quality of these tanks, you would understand -
and the safety valve fitted to the tank has the ability to safely dump
the tanks contents in the event of catastrophic impact.

*Loss of
boot space. If you to remove the original fuel tank and run a
dedicated gas system then this will not be an issue, but if you want
dual fuel or a petrol backup will have to compromise some space in your
boot. No 2 ways about it!

Advantages over other
fuels

The combustion of Autogas is smoother as a result of the higher
octane content. Unlike other fuels, no additives are required
to guarantee high quality.

• Autogas contains no lead and is therefore cleaner
and leaves no residue.

• It is actually better than petrol because it reaches
the engine in pure gas form with improved combustion resulting
and fewer knocking.

• With modern technology, there is hardly any discharge
of carbon monoxide, and compared to petrol and diesel, the
exhaust fumes contain less harmful substances.

• The life of the engine is extended as a result of
the absence of acids and carbon deposits. One can safely state
that engines on LPG last almost twice than that on Petrol/Gasoline.


• Less carbon means less fouling of spark plugs and
points i.e less wear and tear.

• The engine oil does not become diluted with a consequential
reduction in servicing costs.

• Unlike diesel, you do not have to adjust your driving
style. Cold starting is no problem, engine performance is
almost exactly the same as with petrol. There is no spilling
when filling your tank and no possibility of theft or pilfering.
Engine noise is low and you'll be driving in a more environment-friendly
way.

• The environmental advantages of Autogas for automotive
use are indisputable.
